DIBKWASHING APPARATUS.

Application filed April 18, 1920. Serial No. 874,331.

A great majority of houses at the present time are provided with a kitchen sink. With the present invention sucha sink is utilized as a container for the dishes so that the kitchen is not encumbered with devices which take up desirable space. Further such sinks usually have a permanent connection with the sewer and while it is desirable in washing the dishes to be able to utilize the same water several times in order that soap or similar materials may be used it is also desirable to be able to discharge the water without handling directly to the sewer.

In carrying out my invention I provide means for circulating the water preferably connecting this directly with the outlet connection of the sink and provide it with a flexible tube of sullicient length to iermit ot the playing of the water over the dishes contained in the sink and from different tlllg'lts so that all parts of the dishes ma y be reached without a. material change in the location of the dishes. \Vith such a device the ordinary sink may be utilized. The washing may be accomplished through the abrasive action of the-water with such solvents as may be used. The dishes may be thoroughly rinsed while in position.

In carrying my invention forward I also prefer to provide a blower for blowing air,

preferably heated, on to the dishes so as to thoroughly dry them.

Other features of the invention and the details for carrying out the broader features above described will appear more fully from the specification'and claims.

The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a central section through a sink and the discharge connection with the pump connection.

Fig. 2 a section of the motor pump and sewer fitting on the lines 22 in lhgs. 1 and 3.

Fig. 3 a plan view of the operating parts, the sink being removed.

1 marks the sink, 2 the usual discharge vnipple from the sink having a flange 3 arranged at the bottom of the sink and a nut 4 for securing the flange 3 in place. The nipple 2 is screwed into a fitting 5. The fitting has a screw-threaded opening 5 for this purpose. The lower end of the fitting has a screw thread 6 from which a sewer connection 7 leads. A valve seat 8 is formed in the fitting 5 and a valve 9 operates on this seat. The valve is provided with a stem 10 which stem is provided with a spring 11. The upper end of the stem is secured to a crank 12 on a shaft 13. The shaft 13 is provided with a crank 14 by means of which the crank 12 may be turned, thus opening and closing the valve 8. A detent 12 formed on the crank 12 operates in the end of the hearing 13 carrying the shaft 13 and a spring 14" is arranged between the crank 14 and the end of the bearing 13 and this tends to hold the detent 12* in engagement so as to yieldingly lock the valve'9 in closed or open position. v

A centrifugal pump 15 is arranged at the side of the fitting 5, the pump'casing being preferably integral with the fitting. The pump is provided wit-h a. rotor 17 having the vanes 18 having an inlet opening 16 leading from the fitting 5. The pump casing has the usual peripheral discharge opening 19 which leads to a union 20 by means of which a flexible tube 21 is secured to the discharge opening of the pump. The flexible tube 21 is of suflicient length to permit it being carried over the top of the sink and directed downwardly on the dishes carried in the sink and to play on the dishes from different angles in the sink so that Very little changing of position is necessary, the dishes being ordinarily supported in a Wire basket or rack 1 The tube is provided with a valve 22 at its end with a push button 23 by means of which the valve may be opened and closed. It is desirable to have the valve directly at the end of the tube so that the operator may control it as the direction of the stream is controlled. By using the centrifugal pump the valve may be opened more or less or may be completely closed without shutting down the pump. Consequently a large volume of water may be directed on the dishes for ordinary purposes but where greater abraiding effect is required this may be accomplished by reducing the valve area so as to get a more limited and consequently a stream of greater velocity. A rotor' 17 is mounted on the shaft 24. The shaft 24 is mounted in a bearing 25. The bearing 25 is arranged in a cover 27 arranged on the pump case, the cover being secured by screws 28. The covercarries a frame 29 with a flanged end 30 to which a motor 31 is secured by means of screws 32. A motor shaft 33 is connected with the shaft 24 and the pump is driven directly from the motor.

A heater 35 is preferably mounted on the fitting- 5. It is provided with an insulated -heater 35. The heater outer case and is ada ted to heat the water through the wall of the fitting. The heater as shown is provided with an electric heating element 36 receiving its current from the same line 34 as the motor.

A blower or fan 37 is secured to the other end of the motor 31. It has an inlet opening 38 connected by a pi e 39 wlth the as openings 40 so that when the fan is operating air is drawn into the heater and heated by means of the walls of the heater and the heating element and delivered through the pipe 39 to the fan 37. The air is dlscharged from the fan 37 by way of the discharge opening to a flexible tube 42 connected with the discharge opening lay a union 41. Air is delivered from the exible tube 42 by way of a nozzle 43 which nozzle is provided with a butterfly valve 44 in convenient position to be controlled by the operator.

It will be observed that the entire operating unit is mounted on the fitting 5 so that all that is necessary to adapt the ordinary sink for a complete installation of this dev ce is to insert this fitting in the ordinary sink connection. It will be noted also that through the use of the valve 8 the Wash water may be retained in the sink and circulated as often as desired. This is particularly advantageous because it may be desired to economize as to thewater heated. It permits of theuse also of soaps or other materials for facilitating the cleansing of the dishes. By merely opening the valve this wash water may be discharged and rinse water maybe applied and utilized in the same manner as the wash water and also discharged. iAir may be blown upon the dishes, preferably hot air through the heater so as to thoroughly dry them. The

dishes may then be lifted from the sink with the basket so that the sink. is im- 'mediately available for ordinary use.

The sink ma be provided with a strainer 1". This shou d be at least fine enough to catch the larger substances and this may be removed carrying the substances with it.

As shownit is cone-shaped so that such materials are carried up and lodged upon it as the water is discharged.

W hat'I claim as new is 1. In a dish washing apparatus, the combination of a sink; a sewer pipe leading from the sink com rising a fitting; a valve arranged in the tting; a pump carried by the fitting and havin its intake connected with the fitting; an a discharge tube from the pump discharging into the sink.

,2. In a dish washing apparatus, the combination of a sink; a sewer pipe leading from the sink comprising a fitting; a valve arranged in the fitting; a pum carried by the fitting and having its 1I1ta.(8 connected with the fitting; a dischar e tube from the pump discharging into t e sink; and a motor for driving the pump, said motor being also carried by the fitting.

3. In a dishwashing apparatus, the combination of a sink; a sewer pipe leading from the sink comprising a fitting; a valve controlling the connection arranged in the fitting; means extending to the front of the sink for controlling the valve; a pump having its intake connected with the fitting; and a discharge from the pump leading to the sink.

4. In a dish washingapparatus, the combination of a fitting adapted to be inserted in a sewer connection; a valve arranged in the outlet from said fitting; a pump mounted on and communicating with said fittinfg; a motor carried by the fitting; and a exible pipe leading from the pump.

In testimony whereof I have hereunto set my hand.
